    Lower extremity amputations for ischemia showed changes in amputation levels over ten years. While overall healing rates remained similar, diabetic patients had more distal amputations with lower primary healing success.

    Area of Science:

    • Vascular Surgery
    • Orthopedic Surgery
    • Diabetic Complications

    Background:

    • Lower extremity amputations are a common surgical procedure for limb salvage due to ischemia.
    • Trends in amputation levels and outcomes may evolve over time due to changes in patient demographics and treatment strategies.
    • Ischemia, particularly in diabetic patients, presents unique challenges for wound healing and surgical intervention.

    Purpose of the Study:

    • To analyze trends in lower extremity amputation levels for ischemia over a ten-year period.
    • To compare primary healing rates between different time intervals and patient groups.
    • To investigate the impact of diabetes on amputation level and healing outcomes.

    Main Methods:

    • Retrospective review of 324 lower extremity amputations for ischemia.

    Related Experiment Videos

  • Data collection spanning a ten-year period at the University of Oregon Health Sciences Center.
  • Comparison of amputation levels and primary healing rates between the first and second five-year periods, stratified by diabetic status.

    • Main Results:

    • Significant differences observed in the level of lower extremity amputations between the two five-year periods.
    • Overall primary healing rates remained consistent across both five-year periods.
    • Diabetic patients underwent more distal amputations compared to non-diabetic patients.
    • Primary healing rates were lower in diabetic patients undergoing amputation than in non-diabetic patients.

    Conclusions:

    • Changes in amputation level strategies for lower extremity ischemia occurred over the decade studied.
    • Diabetes mellitus is associated with more distal amputations and poorer primary healing outcomes.
    • Continued monitoring of amputation trends and outcomes is crucial for optimizing patient care in ischemic limb disease.
